Print mdi child form

[rexyrexin]

I am making a windows application. I have written the code for printing the active mdi child using PrintForm in c#. The problem is that my forms are big so they do not come fully on the screen i.e. they are scrollable. Now when I print the form, I do get the full form. I also used the scrollable but its no use.
The code is:

if (this.ActiveMdiChild == null)
            {
                return;
            }
            printForm1.Form = this.ActiveMdiChild;
            printForm1.PrintAction = System.Drawing.Printing.PrintAction.PrintToPrinter;
            //printForm1.Print();
            printForm1.Print(this, PrintForm.PrintOption.Scrollable);

Can someone help me and tell me how to get the full form along with the data. Please don't tell to capture the screenshot as the form is scrollable.
